NBCnews - Taylor Swift's Eras Tour shows in Vienna have been canceled because of what Austrian police say was a planned ISIS terrorist attack targeting the concerts.

"With confirmation from government officials of a planned terrorist attack at Ernst Happel Stadium, we have no choice but to cancel the three scheduled shows for everyone’s safety," Barracuda Music, an event organizer in the city, posted Wednesday evening on Instagram.

Taylor Nation, an Instagram account run by Swift's team, reposted the message to its story.

According to the post, all tickets will be refunded and ticketholders can visit a website to request refunds.
